SKATE.

SPECIFICATION forming part of Letters 'Patent No. 572,501, datedDecember 1, 1896. Application filed February 19, 1896. Serial No.579,819. (No model.)

To all whom it may concern,.-

Beit known that I, HENRY D. CARRYL, a citizen of the United States,residing in the city and county of ANew York, State of New York, haveinvented certain new and useful Improvements in Skates, of which thefollowing is a specification, reference being had to the accompanyingdrawings, forming a part hereof.

This invention relates in general to the construction of skates, and hasfor its object the provision of improved means whereby a skate may belengthened or shortened to adapt it to shoes of different lengths.Various means having this general object in view have been devisedheretofore, but they are for the most part either unnecessarilycomplicated or require the use of a wrench or other tool to eifect thedesired adjustment, or have dezo tachable parts, such as thumb-nu ts,which are liable to be lost and thereby to render the skate useless forthe time being. I have sought vto provide means for this purpose whichshall be extremely si mple'in construc- 2 5 tion, shall require no keyor other tool for their adjustment, and shall have no detachable partsto be lost.

I have herein shown and described my improvements as adapted to aroller-skate, but

3o it will be understood that they might be appliedto skates of otherform and construction.

The various features of improvement wherein my invention consists willbe fully described hereinafter with reference to the ac- 3 5 companyingdrawings, in which- Figure l is a side View of a roller-skate to whichmy improvements are applied. Fig. 2 is a perspective view of the samewith the parts separated somewhat to enable their 4o construction to bemore clearly represented.

Fig. 3 is a bottom View of the skate in condition for use; and Fig. 4.is a bottom view of a portion of the extensible foot-plate, showingfeatures of construction which are obscured in Fig. 3.

In the skate which I have chosen for illustration in the drawings thefoot-plate is formed in two parts, a toe-plate A and a heelplate B, towhich are respectively secured in 5o a suitable manner the bearings forthe front rollers C and the rear rollers D. The toeplate A is providedwith toe-clamps E E, which are constructed and arranged to operate inthe usual manner, and the heel-plate B is provided with a slidingheel-clamp F.

' The toe-plate A and heel-plate B are provided, respectively, withtongues A and B', which overlap, the tongue A' preferably overlying thetongue B and the latter sliding through the bracket c, which supportsthe front rollers C, and between the inner end of the curved toe-clampsE E and the toe-plate A. Its forward end is preferably slotted, as atb,to engage the headed stud a., which is secured to the toe-plate, andalso to permit movement of the stud e, which connects the toe-clamps tothe link hereinafter referred t0 and plays to and fro in a slot in thetoe-plate. The rear end of the tongue A' is provided with a pin or studor other projection a', which is adapted to enter any one of a series ofholes b' in the heel-plate B and its tongue B', whereby the two parts ofthe foot-plate may be retained in the relative longitudinal positiondesired, according to the length of the foot on which the skate is to beused.

To retain the tongue A' in engagement with the heel-plate B, I prefer tomake use of the adjustable heel-dog, which is clearly shown in Figs. 1and 2. As there represented, it comprises a slide Cr, which embraces thetwo tongues A' and B', and has pivoted between engage the heel at itsupper end and at its lower end to engage the rou ghened or serratedsurface a' of the tongue A'. Vhen the dog H is disengaged from theserrations, the slide can be moved to and fro upon the two tongues A'and B', and when it is moved forward to the position represented in Fig.2 the tongue A' can be sprung upward sufficiently to disengage the pina', from the heel-plate B and to permit the longitudinal adjustment ofone plate with respect to the other. When, however, the slide is in theposition represented in Fig. 1, the tongue A' is held positively fromdisengagement from the heel-plate, whereby the two parts of thefoot-plate are locked in adjusted position.

The heel-clamp F is carried by a tongue F', which slides 4freely throughthe bracket d, which supports the rear rollers D. It may be IOO bentdownwardly, as indicated, to avoid interference with the slide Gr, andlat its forward end has pivoted thereto the clamping-lever I. The latteris provided with an eccentric stud i for engagement in any one of aseries of open notches 7c, which are formed in the edge of the link K,to which the toe-clamps E E are pivotally connected. The notches 7s kcorrespond to the holes b' b' in the heel-plate B, and the stud t' willbe engaged with that one of the notches 7c 7c which corresponds inposition with that one of the holes b h which is entered by the pin a ofthe tongue A. When the clamping-lever is engaged with the lin-k in themanner described, it operates in the usual and well-known manner to drawthe heelclamp F forward to clamp the heel between itself and theheel-dog and to draw the toeclamps together to clamp the sole of theshoe between them.

It is obvious that the clamping devices are capable of easy adjustmentaccording to the length of the foot-plate, and that the length of thefoot-plate can be easily and quickly changed and secured against thepossibility of slipping. Moreover, there are no parts to become detachedand lost and no key, wrench, or other instrument or tool is required toassist the fingers of the operator. Furthermore, the construction isexceedingly simple and inexpensive and the skate is not weakened at anypoint.

What I claim, and desire to secure by Letters Patent, is-

l. In a skate, the combination with a toeplate and heel plate havingoverlapping tongues, one of said tongues being adapted to engage theother tongue, of a sliding heeltongues, one of said tongues beingadapted to engage the other tongue to prevent longitudinal movement, anda slide formed to embrace both of said tongues and to be moved thereonto prevent or permit disengagement of the one tongue from the other, oftoeclamps carried by said toe-plate, a clampinglever carried with saidheel-plate and having an eccentric stud, and a link to which saidtoe-clamps are connected, said link being formed to engage saideccentric stud at different points in its own length, substantially asshown and described.

3. In a skate, the combination with a footplate composed of a toe-plateand a heel-plate adjustable longitudinally with respect to each other,of sliding toe-clamps carried by said toe-platea lon gitudinally-slidingheel-clamp mounted on said heel-plate, a clamping-lever carried by saidheel-plate and a link to which said toe-clamps are connected, said linkbeing formed for adjustable engagement with said clamping-lever,substantially as shown and described.

This specification signed and witnessed this 15th day of February, A. D.1896.
